COTTON-PICKING- DEVICE.

Specification of Letters Patent.

Patented June 3, 1919.

Application filed February 1, 1918. Serial N 0. 215,530.

To all whom it may concern:

Be it known that I, JAMns H. O. Bore, a citizen of the United States, residing in the city of Oklahoma, county of Oklahoma, and- State of Oklahoma, have invented certain new and useful Improvements in Cotton- Picking Devices, of which the following is a specification.

My invention relates to cotton picking devices, and more particularly to a pneumatic cotton picking device of the character shown and described in my United States Patents, 1,239,343, issued September 4, 1917, Number 1,253,774, issued January 15, 1918.

The principal object of my present invention is to further improve and simplify my said cotton picking device. I accomplish this improvement by combining my fan and ball bearing mechanism, and by simplifying the construction and arrangement of the parts of the casing, whereby said casing and the mechanisms therein are more easily assembled for use.

In order to more fully explain said invention, I have illustrated a practical embodiment thereof on the accompanying sheet of drawings, which I will now describe. In the drawings,

Figure 1 is a top plan View thereof with parts shown in horizontal section on line 1'1, and line 44, of Fig. 2;

Fig. 2 is a vertical longitudinal sectional view of my improved cotton picking device; and

Fig. 3 is a horizontal sectional view, sections being shown on lines 22, 33, and 44, of Fig. 2.

Referring now more in detail to the drawings, my improved cotton picking device as here illustrated, comprises a body or casing made in three sections, designated, respectively, 1, 2 and 3, section 1, being adapted at its lower end to be attached to a cotton picking pipe 4, and at its upper end provided with an inner annular flange 5, forming a ball run or bearing, and an outer annular flange 6, above which the upper end of said section 1 is externally threaded, as at 7.

Section 2 of said casing is provided at its lower end with an annular enlargement 8, internally threaded for attachment to the threaded upper end of section 1 of said casing. Said section 2 is also provided in its body with a series of inlet holes 9, 9, with a damper ring or band 10, also provided with holes and mounted around said casing 2, between annular holding brackets 11, 11. Said damper ring can be turned on said caslng, whereby the holes therein can be brought wholly or partially into register with the holes in the side of said section 2, whereby to admit more or less air through said holes, as may be desired.

Section 3 of said casing is internally threaded at its lower end and thereby adapted to be attached to the upper end of section 2, as at 12. Said end section 3, at its up per end is turned inwardly, whereby to form an inwardly projecting annular flange 3 Rotatably mounted in said body or casing, is a tubular member 13, made in two sections,-13 and 13 threaded at their meeting ends as at 13 Mounted on the up er end of the section 13*, is a bearing mem er 14, in the outer edge. of which is provided a ball race to receive the balls 15, which bear against the inner face of the upper end of section 2 of said outer casing. The upper end of section 13 of said inner tube fits loosely around the inturned flange 3*, as shown. Mounted on the lower end of said tubular section 13 is a fan 16, the blades of which at their outer ends carry an annular ring 17, having formed therein a ball race to receive balls 18, which run therein and in the shoulder formed in the annular enlarged portion 8 of the middle section 2, of said outer casing. A ball race is also pro vided in the under face of said bearing ring 17, in which the balls 19 run, between said bearing ring 17 and the inner annular flange 5, formed on the upper end of section 1 of said casing. These balls support said bearing ring 17 the fan 16, and the inner tubular member 13.

At their inner ends said fans are secured to a collar 16 around said tubular member 13*. Connecting bars 16 also connect the collar 16 and the bearing ring 17 and strengthen the fan bearing ring structure.

As suction is applied through the conveying tube 4, to which said casing is attached, a current is set up through said casing in said tubular member 13 for drawing in the cotton bolls, and also through the holes 9 in said outer casing and through the fan 16, resulting in the rotation of said fan and said tubular member 13, and thus more effectively passing the cotton balls through said tubular member 13, because it is revolving and into the cotton conveying tube 4.

It will be understood, of course, that changes can be made in the structure as here.

1. In a cotton picking device, a body, a

tubular member axially and rotatably mounted in said body, a fan structure mounted around said tubular member, and a ball bearingsupporting mechanism around the outer edge of said fan, secured thereto, and operating between said fan and said body for revolubly supporting said tubular member.

2. In a cotton picking device, an outer casing made in three sections, screwed together, a tubular member axially and revolubly mounted in said casing, a fan around said tubular member within said casing, and ball bearing supporting means around said fan and between said casing and-said fan,- substantially as described.

' of said tubular member, annular bearing rlngs arranged one around sald tubular member intermediate its ends and another around the outer periphery of said fan, and between said fan and the inside of said outer casing, and ball bearings mounted between said rings and the inside of said outer casing for rotatably supporting said fan and said tubular member, substantially as described.
